摘要
引入了MLW-环与MELW-环的概念,并得到了下面2个主要结果:1)若R是MLW左SPF环,则R/J(R)是强正则环;2)若R是Abelian的MELW-环,并且每一个单奇异左R模是GP内射模,则R是reduced弱正则环.
The concepts of MLW-rings and MELW-rings are introduced and the following two results are mainly obtained: 1) If R is a MLW-left SPF-ring, then R/J (R) is a strongb; regular ring;2) If R is an Abelian MELW-ring whose every simple singular left R-module is GP-injective, then R is a reduced weakly regular ring.
